Bradley’s endlessly entertaining follow-up to 2009’s The Sweetness at the Bottom of the Pie finds precocious 11-year-old Flavia de Luce once again indulging her curiosity about corpses. Wandering near her threadbare ancestral home in early 1950s England, Flavia bumps into famed TV puppeteer Rupert Porson and his pregnant wife, who have been marooned by an ailing van. While they wait for repairs to be completed, they agree to put on a performance for the village of Bishop’s Lacey—but Rupert’s sudden death ends the show. Feigning an innocence entirely at odds with her shrewdness about adult doings, Flavia uses her skills in chemistry and questioning to puzzle out which of the many possible suspects murdered Rupert and why. The author deftly evokes the period, but Flavia’s sparkling narration is the mystery’s chief delight. Comic and irreverent, this entry is sure to build further momentum for the series. (Mar.)
